ok i doubt there is anything anyone here can tell me that i have not tried but who knows.
symptoms:
extremely hard to start(clutch is catching fine)
once started it will not stay running, boggs down, have to keep pedaling to make teh engine continue to turn over. holding thrott full while pedaling to make the motor catch while clutched. and have to keep pouring teh thrott to keep the engine barely running.(have tried every carb adjustment known to man).
as far as the carb goes we (al.fisherman and myself) have changed teh intake back to a non-ported(for boost) manni, tried 3 of 5 needle positions, changed and replaced the gasket, checked the float positioning, CHANGED CARBS COMPLETELY, nothing is working from that end and teh issue still persists.
no power when the engine is running, will not carry itself.
and tone sounds too deep to me like it is trying to bogg just running while pedaling. will not stay running on its own.
this is an 80cc HT kit, the very same that Al.Fisherman and myself made the taredown tutorial out of. so we know that everything inside the engine is correctly installed. one note of interest tho.
**NOTE**
during the taredown, we could not save and did not replace the lower jug/cylinder gasket (base gasket). we have made our own but i fear that it is not thick enough. could be part of the issue but im not a mechanic so i would not know.
**Secondarily**
WATCH YOUR HEAD GASKETS!!!!
i originally had a tick/rattle in the engine, (thus the reason for the taredown) come to find out that the ticking was teh SBP Head gasket.
when matched with SEVERAL other head gaskets both original and more SBP gaskets, some of them, the inner cut was not matching to the piston stroke, not perfectly circular, stacked together we found that not only were a couple from SBP uneven, but other originals were too. the piston was hitting the uneven part of the gasket.
it ran fine thru the whole break in and now it is nothing but junk(or at least i am starting to think so, again not a mechanic). i would just like it to run. i can get teh rest. or does it just need to R.I.P?
